This item is a DBH radial shaft seal, identified by part number 5402. Its dimensions are 25 mm shaft diameter (d), 41.17 mm housing bore diameter (D) and 9.52 mm height (h). The Lz design corresponds to a single sealing lip, suitable for lubricated rotating shafts. The 5402 designation makes it easy to locate in catalogues and ordering systems. It is a common replacement part in industrial equipment that requires oil or grease retention and protection against dust and dirt.

Typical applications include gearboxes, centrifugal pumps, electric motors, conveyor rollers and belt or chain drive systems. In all cases, the oil seal prevents lubricant leaks and the ingress of particles, extending the service life of bearings and gears. It is also used in process equipment, machine tools and industrial vehicles where mounting space is limited and reliable sealing is required.

To select an oil seal correctly, check that the shaft, housing bore and height dimensions match those of the housing and shaft. The Lz design is suitable for moderate peripheral speeds and low pressures. During installation, lubricate the lip with compatible grease, insert it perpendicular to the shaft and avoid damaging the lip with sharp tools. If the shaft shows wear, consider using a repair sleeve or an alternative size.
